Obesity Linked to Prostate Cancer Recurrance

Obesity increases the risk of prostate cancer recurrence in both black and white men, says a U.S. study that challenges previous research suggesting obesity may be more significant for black men.

"Not so. Obesity leads to worse cancer in both groups," study senior author Dr. Stephen Freedland, an associate professor of urology and pathology at the Duke University Medical Center Prostate Center, said in a news release from the school.

Freedland and study author Dr. Jayakrishnan Jayachandran, a urology oncology fellow, examined the medical records of 1,415 prostate cancer patients who had undergone a radical prostatectomy. They found that race had no influence on the relationship between obesity and the aggressiveness of the cancer.

"We found that higher BMI [body-mass index] was associated with significantly increased risk of cancer recurrence for both blacks and whites," Jayachandran said in the news release.
